| Abstract: | As the use of MP3 audio compression increases, the demand for the insertion of additive data such as copyright information or information on music content itself continues to grow, and related research has also progressed actively. When additive data is inserted in MP3 bitstream, it should not cause any distortion in music quality or change the file size due to the modification of MP3 bitstream structure. To satisfy these conditions, some additive data were inserted in bitstream by modifying some linbits among the quantized integer coefficients having big values. The characteristics of linbits and their distribution were also considered. As a result of subjective sound quality evaluation through the Mean Opinion Score (MOS) test, the quality of MOS 4.6 was confirmed to be achievable at the data insertion rate of 60 bytes/sec. Using the proposed method, it is possible to insert additive data effectively into encoded bitstream and to retrieve it easily; thus realizing various applications such as audio database management. | ||
